Video sensor node energy preservation through dynamic adaptive video encoding parameters' values selection

Othmane Alaoui-Fdili, François-Xavier Coudoux, Youssef Fakhri, Patrick Corlay, Driss Aboutajdine

Wireless video sensor networks (WVSN) are energy constrained systems where deployed video nodes are capable of capturing the visual scene, performing local processing such as video compression, then routing the results toward the destination. In this paper, we consider the problem of minimizing the…

Quantum confinement effects in Pb nanocrystals grown on InAs

Tianzhen Zhang, Sergio Vlaic, Stéphane Pons, Alexandre Assouline, Alexandre Zimmers, Dimitri Roditchev, Hervé Aubin, Guy Allan, Christophe Delerue, Christophe David, Guillemin Rodary, Jean-Christophe Girard

In the recent work of Vlaic et al. [Nat. Commun. 8, 14549 (2017)], it has been shown that Pb nanocrystals grown on the electron accumulation layer at the (110) surface of InAs are in the regime of Coulomb blockade. This enabled a scanning tunneling spectroscopy study of the superconducting parity…

Surface morphology, structural and electrical properties of RF-sputtered ITO thin films on Si substrates

Ahlem Lebbad, Laid L.KERKACHE Kerkache, Abdelhamid Layadi, Floriane Leroy, Bandar Alshehri, El Hadj Dogheche

Series of indium tin oxide (ITO) thin films were deposited onto Si(100) substrate by RF sputtering. The film thickness ranges from 61 to 768 nm. X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM) experiments were performed to study the structure and the…

Optimization and improvement of a front graded bandgap CuInGaSe2 solar cell

Abdelkader Aissat, H. Arbouz, Jean-Pierre Vilcot

This paper reports simulations of gradual bandgap CIGS absorber and its impact on the characteristics of a solar cell. The bandgap of the CIGS absorber varies linearly and drops from Egmax (at the junction limit) to Egmin (in the vicinity of the rear contact).We introduce an effective absorption…

Evidence for recombination-induced degradation processes in InGaN-based optoelectronic devices

Carlo de Santi, Matteo Meneghini, Alessandro Caria, Nicola Renso, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Enrico Zanoni, Gaudenzio Meneghesso

For the first time, we demonstrate recombination-induced defect generation in InGaN/GaN-based optoelectronic devices, by stressing InGaN/GaN high periodicity MQW structures: the results will significantly improve the understanding of the degradation of LEDs, lasers and photodetectors, sinceso…
